    There is broad agreement that the next major collider should include an e⁺e⁻ Higgs factory mode. Yet, given the remarkable progress expected from the HL-LHC, I argue that a program focusing too heavily on Higgs coupling measurements is not ambitious enough, be it linear or circular. The critical question is what additional capabilities each design offers. Circular machines provide unparalleled...

    Talk

    Within the framework of the Standard Model Effective Field Theory (SMEFT), next-to-leading order (NLO) calculations reveal sensitivities to a broad class of higher-dimensional operators, including those affecting top quark interactions, Higgs couplings, and potential sources of CP violation, that may remain hidden at leading order.

    In this talk, I will highlight recent advances in NLO SMEFT...

    We present results from a global fit of Standard Model parameters and dimension-6 SMEFT Wilson coefficients that includes electroweak, Drell-Yan, Higgs-boson, top-quark, and flavour observables. Fits obtained by floating individual coefficients are also discussed. The leading-order scale dependence of the SMEFT Wilson coefficients is consistently included in the evolution from the UV scale to...

    I will present a global study of the reach in Higgs, electroweak, and top quark couplings at the future high-energy particle colliders proposed in the context of the European Strategy for Particle Physics 2026 Update (ESPPU26). I will discuss electron-positron circular (FCC-ee, CEPC) and linear (LCF) colliders. The global fit results, produced with the latest version of the SMEFiT code, take...

  5. 56. Assessing uncertainties arising in the interpretation of single-Higgs-production observables as a measurement of the triple Higgs coupling

    Talk

    e+e- colliders operating at energies below the di-Higgs production threshold can provide information on the trilinear Higgs self-coupling lambda via its loop contributions to single Higgs production processes and electroweak precision observables. We investigate how well a non-SM value of lambda can be determined indirectly via its loop contributions to a global EFT fit. Using a doublet...

    Determining Triple Gauge Boson Couplings at 250 GeV Higgs Factories

    We study the extraction of (anomalous) $ZWW/\gamma WW$ triple gauge couplings (aTGC) in the $e^+e^-\rightarrow \ell\nu q\bar{q}$ process at $250\,\text{GeV}$ from full simulation and reconstruction with the ILD detector.
    Determining aTGC at the sub-permille level is vital for the precise and consistent determination of...

    Placeholder abstract, invitation to CMS conference committee sent by Marcel Vos

    The Standard Model Effective Field Theory forms a powerful framework
    to interpret the wealth of precision measurements from the LHC
    experiments. In this contribution, a review is presented of global
    fits by ATLAS and CMS of the SMEFT coefficients.
